VALVE.

Application filed April 12, 1924.

To all whom it may concern.-

Be it known that I, STEPHEN STUGKY, a citizen of the United States, residing at Anniston, in the county of Calhoun and State of Alabama, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valve constructions, and. more particularly to a valve de signed for use within a toilet or closet tank, the valve being designed to permit a float actuated valve to be removed from the valve casing for the purpose of repair, at which time an automatically operable pressure valve will be seated to prevent overflow of the tank, both of said valves operating in unison when arranged within the valve casing.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a sectional view through a. tank showing the valve construction in elevation.

Figure 2 is an enlarged vertical sectional viewthrough the valve structure.

l igure 3 a sectional view taken on the line 33 of Figure 2.

Figure l is a sectional. view taken on the line l.-4t of Figure 2.

Referring to the drawing in detail, 10 indicates a flush tank of well known construction into which extends a water supply pipe 1.1, and upon the upper end of which is sup ported the valve casing of the construction clearly illustrated in Figure 2. In this tigure, it will be noted that the valve casing is formed with reduced tubular end portions 12 and 13 respectively, the former being threaded or otherwise secured onto the upper end of the supply plpe 11, while the latter is designed to receive the float controlled slide valve. The intermediate portion 1% of this valve casing is enlarged, and is divided by a partition 15 into upper and lower compartments, the latter accommodat- Serial No. 706,150.

ing a pressure valve indicated at 16 and of a size to slidably enter the reduced tubular portion 12. The opposite sides of the partion 15 constitute valve seats for the respective valves above mentioned, and the partition is provided with a central opening 17 through which the water passes from the lower compartment of the valve casing into the upper compartment as will be readily understood. Projecting laterally from one side of the enlarged intermediate portion 1t ot' the valve casing is an extension 18 of elongated contour in plan, which extension is of hollow formation and communicates with the adjacent compartment of the valve casing. Depending from the lower wall of this extension is a water discharge pipe 19, while rising from the upper wall of the extension is an atterflll pipe 20.

The float actuated valve is formed with spaced heads 21 and 22 respectively which are connected by a stem indicated at The head 21 is formed with an annular groove 24 which of course defines what is termed a flange 25 at the inner edge of the head. A float 26 is carried by one end of a lever 27 tulcrumed as at 28 upon apertured cars 29 forming part of the valve casing, and the inner end of this lever is forked or bifurcated as at 30 to straddle or embrace the flange'or edge 25 above referred to. By reason of this connection between the lever 27 and the float actuated valve, it is manifest that when the float is elevated within the tank incident to the admittance of water thercinto, the said valve is lowered against its seat 15, and conversely, when the float is lowered with the fall of the level of water, the seat is elevated to an opened position. This position of the valve is illustrated in Figure 2. The head 22 01 this valve is formed with an annular groove 31 to accommodate a suitable packing 32, while the bottom of said head is recessed to receive a disk of felt or other relatively soft material 33 or" a size to completely close the opening 1.7 when this valve is seated. Depending from this valve and secured thereto in any suitable manner is a pin 3 1 which is kerfed at its lower end to accommodate a projection rising from the head 36 of the pressure actuated valve 16 above referred to. It will be noted from an inspection of Figures 2 and 3 that the body of this valve is elongated and corrugated longitudinally, to allow the water to pass beyond the body of the valve as it leaves the inlet pipe 11, finding its way into the upper compartment of the valve casing. Now, when the water is admitted to the tank 10, the float actuated valve, and the pressure operated valve moves down wardly in unison, and when the level of water is lowered within the tank, thereby resulting in the fall of the float 26, the valves rise in unison, one valve being actuated by the float and the other by the pressure of water entering from the pipe 11.

In practice, assuming that the level of water in the tank 10 has been lowered, and the valves opening into the position shown in Figure 2, the water enters the valve casing from the supply pipe 11 and passes around the valve 16 through the opening in the valve seat and thence through the extension 18 from where it passes through the pipe 19 into the tank 10. As the level of water rises within the tank, the float 2G is raised, and the float actuated valve is gradually lowered until it is seated against its seat 15. Some water will be taken care of by the afterfill pipe 20 as will be readily understood. If for any reason, it is necessary to remove the float actuated valve from the valve casing, it is only necessary to lower the lever 27 to the limit of its movement in a downward direction, whereupon the said valve can be easily separated from the forked extremity of said lever, and subsequently lifted from the valve casing. When the valve is thus removed and separated from the valve 16, the pressure of water entering from the pipe 11 closes the valve 16 and holds the latter seated, thereby permitting the float actuated valve to be repaired without cutting off the supply of water at an appropriate point in the water system, which is usually in the cellar of the building.

Vhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim:

1. In combination, a valve casing having an enlarged central portion, a partition arranged therein and dividing said casing into upper and lower compartments, said partition having a central opening, a hollow extension projecting laterally from the casing and communicating with the compartment arranged above the partition, a pipe depending from said extension, an afterfill pipe rising from said extension, a float actuated valve operating within the casing above the partition, a pressure operated valve operating within the casing beneath the partition, and capable of being automatically seated against the partition when the float operated valve has been removed from the casing, and a connection between said valves whereby the latter are reciprocated in unison.

2. In combination, a valve casing open at both ends and adapted to be supported upon a fluid supply pipe, a partition arranged centrally of said casing and having an opening therethrough, a valve arranged to slide within the casing above the partition and formed with an annular groove, a float actuated lever pivoted on the valve casing and having a forked extremity to embrace an edge, of the valve when received in said groove, a pin depending from said valve and passed through the opening in said partition, a pressure operated valve arranged within the casing beneath said partition and associated with said pin, whereby said valves reciprocate in unison, said last mentioned valve being automatically seated and held seated by pressure of the water from the supply pipe, subsequent to the removal of the float actuated valve from said casing, a water discharge pipe leading from the casing and communicating therewith at a point above the partition, and an after-fill pipe supported by said casin in testimony whereof I a tlix my signature.
